foldwork-dev/mcp-injector

What it does

foldwork-dev/mcp-injector is a Model Context Protocol (MCP) server that runs locally on your machine to dramatically optimize how AI tools interact with your codebase. It preindexes your entire codebase into a SQLite catalog and serves compressed Abstract Syntax Tree (AST) snapshots to Claude Code, Cursor, and VS Code, enabling intelligent code queries with minimal token consumption.

How to set up

Installation involves cloning the repository from GitHub and running the local MCP daemon on your development machine. Configure your Claude, Cursor, or VS Code instance to connect to the MCP server endpoint. The tool automatically indexes your codebase on startup and maintains the SQLite catalog for subsequent queries.

• Reduces token usage by up to 4189% on real-world codebases
• Compatible with Claude Code, Cursor, and VS Code
• Verified performance across Django, Tokio, Gin, and other major frameworks
• Cross-platform support (macOS, Windows, Linux)
